The recycling impact calculator shows CO2 and energy saved by recycling common materials. Aluminum recycling is especially impactful — it saves 95% of the energy needed to make new aluminum from ore — while glass and plastic savings vary significantly by type.
Weekly Recycling (per person)
Based on EPA emission factors. Actual savings vary by local recycling infrastructure.
How to Calculate Your Recycling Impact
Enter your weekly recycling quantities for each material type. The calculator shows annual CO2e savings and which material gives you the most environmental benefit per pound recycled.
Material Breakdown
Aluminum has by far the highest CO2 savings per pound recycled — about 4 kg CO2e per pound. Paper is second at about 0.7 kg CO2e per pound. Plastic varies greatly by type; PET and HDPE save about 0.6-0.7 kg CO2e per pound when actually recycled. Glass saves about 0.14 kg CO2e per pound.
Getting Accurate Estimates
Weigh your recycling bins before taking them out — this gives a more accurate picture than estimating. Many households recycle 15-30 lbs of materials per week without realizing it. Cardboard boxes from deliveries alone can add up to 2-5 lbs per week for active online shoppers.

How much CO2 does recycling aluminum save?
Recycling aluminum saves 95% of the energy required to produce virgin aluminum from bauxite ore. Recycling 1 kg of aluminum saves about 9 kg of CO2e. A single recycled aluminum can saves enough energy to power a TV for 3 hours. Aluminum is one of the most valuable materials to recycle.
How much CO2 does recycling paper save?
Recycling 1 tonne of paper saves 3.3 trees, 2.5 barrels of oil, and about 1.6 tonnes of CO2e compared to producing virgin paper. Recycling paper also reduces water use by 60% and uses 65% less energy than producing from virgin wood pulp.
Is glass worth recycling?
Glass recycling saves 30% of the energy needed to make new glass from raw materials. Recycling 1 kg of glass saves about 0.3 kg CO2e. While less dramatic than aluminum, glass is 100% recyclable indefinitely without quality loss. The main benefit is landfill diversion — glass takes 1 million years to naturally decompose.
Does recycling plastic actually help?
Plastic recycling varies greatly by type. PET (type 1, water bottles) and HDPE (type 2, milk jugs) are effectively recycled, saving 1-1.5 kg CO2 per kg recycled. Types 3-7 are rarely recycled economically. Recycling 1 kg of PET plastic saves about 1.4 kg CO2e compared to virgin production.
